Persist embedded resources as :text instead of :map

In my app I'm using Cocktail (https://hexdocs.pm/cocktail) to manage scheduled events which I'd like to save to a text field using Cocktail.Schedule.to_i_calendar/1. What I have so far: I use an embedded schema to generate the API used in LV forms and GraphQL

defmodule Schedule do
  use Ash.Resource,
    data_layer: :embedded,
    extensions: [AshGraphql.Resource]

  graphql do
    type :schedule
  end

  attributes do
    attribute :count, :integer
    // ...
  end

  validations do
    validate numericality(:count, greater_than: 0)
  end
end

defmodule Schedule do
  use Ash.Resource,
    data_layer: :embedded,
    extensions: [AshGraphql.Resource]

  graphql do
    type :schedule
  end

  attributes do
    attribute :count, :integer
    // ...
  end

  validations do
    validate numericality(:count, greater_than: 0)
  end
end

Which I use in another resource

attributes do
  integer_primary_key :id

  // ...

  attribute :schedule, Schedule

  // ...
end

attributes do
  integer_primary_key :id

  // ...

  attribute :schedule, Schedule

  // ...
end

And then realized that embedded schemas are persisted as maps and I haven't found a way to change this behaviour

def up do
  alter table(:table) do
    add :schedule, :map
  end
end

def up do
  alter table(:table) do
    add :schedule, :map
  end
end

I've also briefly tried setting up a custom type instead without much success.

Users getting logged out every few hours

I recently switched our auth from phx.gen.auth to AshAuthentication. The switch was very smooth and users didn't notice anything except for one detail: they're now getting logged out every few hours (exact time seems to vary). I've been going through all documentation and the Discord but haven't found anything related. The only thing I found was this option token_lifetime, changing the value hasn't helped so far, though. Any ideas what could be happening or were I can start debugging?

How to create has_one relationships in a nested form

I have a resource called Transaction that has a has_one relationship with a resource called RecurrencePattern. When creating a new transaction (usually through a form in LV) I want to also create a matching recurrence_pattern. This works great when using the create action directly, but I'm getting an error when using an AshPhoenix.Form (I believe I got it to work at some point but don't know how to get back there again 😅 ) This works:

Transaction.create!(%{
  amount: 100,
  description: "Test transaction",
  date: Date.utc_today(),
  category_id: context.category.id,
  currency_id: context.currency.id,
  method_id: context.method.id,
  rate_id: context.rate.id,
  type_id: context.type.id,
  end_date: Timex.shift(Date.utc_today(), months: 1),
  recurrence_pattern: %{
    recurrence_type_id: context.recurrence_type.id,
    count: 5
  }
})

Transaction.create!(%{
  amount: 100,
  description: "Test transaction",
  date: Date.utc_today(),
  category_id: context.category.id,
  currency_id: context.currency.id,
  method_id: context.method.id,
  rate_id: context.rate.id,
  type_id: context.type.id,
  end_date: Timex.shift(Date.utc_today(), months: 1),
  recurrence_pattern: %{
    recurrence_type_id: context.recurrence_type.id,
    count: 5
  }
})

This gives me an error:

params = %{
  amount: 100,
  description: "Test transaction",
  date: Date.utc_today(),
  category_id: context.category.id,
  currency_id: context.currency.id,
  method_id: context.method.id,
  rate_id: context.rate.id,
  type_id: context.type.id,
  end_date: Timex.shift(Date.utc_today(), months: 1),
  recurrence_pattern: %{
    recurrence_type_id: context.recurrence_type.id,
    count: 5
  }
}

transaction =
  AshPhoenix.Form.for_create(Transaction, :create,
    api: Transactions,
    forms: [auto?: true]
  )
  |> AshPhoenix.Form.add_form(:recurrence_pattern)
  |> AshPhoenix.Form.validate(params)
  |> AshPhoenix.Form.submit!()

params = %{
  amount: 100,
  description: "Test transaction",
  date: Date.utc_today(),
  category_id: context.category.id,
  currency_id: context.currency.id,
  method_id: context.method.id,
  rate_id: context.rate.id,
  type_id: context.type.id,
  end_date: Timex.shift(Date.utc_today(), months: 1),
  recurrence_pattern: %{
    recurrence_type_id: context.recurrence_type.id,
    count: 5
  }
}

transaction =
  AshPhoenix.Form.for_create(Transaction, :create,
    api: Transactions,
    forms: [auto?: true]
  )
  |> AshPhoenix.Form.add_form(:recurrence_pattern)
  |> AshPhoenix.Form.validate(params)
  |> AshPhoenix.Form.submit!()

The error inside the changeset:

%Ash.Error.Changes.Required{
  field: :transaction_id,
  type: :attribute,
  resource: RecurrencePattern,
  changeset: nil,
  query: nil,
  error_context: [],
  vars: [],
  path: [],
  stacktrace: #Stacktrace<>,
  class: :invalid
}

%Ash.Error.Changes.Required{
  field: :transaction_id,
  type: :attribute,
  resource: RecurrencePattern,
  changeset: nil,
  query: nil,
  error_context: [],
  vars: [],
  path: [],
  stacktrace: #Stacktrace<>,
  class: :invalid
}
